--- Comment #2 from Philby John philbyjohn@gmail.com 2011-05-27 08:38:31 CDT --- I think this is a case of multiple function definitions and very long path name to the actual file. The crash happens if you have multiple function definitions. A pop up opens and then Wine crashes.
I haven been trying various ways to create a generic approach to replicate the problem but haven't been successful so far, except for that specific instance of the project. Btw, I use Source Insight to majorly look at Linux kernel source which is a relatively big project with thousands of files and numerous paths.
I will need to dig more.
